The reason the iPhone that fell 16,000ft from Alaska Airlines flight didn’t crack

Unless you’ve been living under a rock, you probably heard about the recent Alaska Airlines incident.

It was a scary reminder that small errors can have massive consequences, but the event featured some small miracles.

Firstly, nobody was sitting in the window seat where the door blew out and secondly, there was an iPhone discovered on a road side that, despite falling 16,000 feet, was still “perfectly intact”.

But it begs the question: how can an iPhone fall from that height and its screen not break?

Interestingly, it’s not the first time a phone has reportedly survived a fall from a plane.

One fell from 1,000 feet in 2018 and another, from 9,300 feet, in 2015.

On these occasions, there was no disaster – the planes were small enough that the phones were accidentally dropped out of them.

According to Collin Wilkinson, the director of the Center for Glass Innovation at Alfred University, the resilience of these phones can partly be attributed to the fact smartphone screens have steadily improved over the years.

But if that’s the case, why do phones still break falling from clumsy hands and kitchen tables?

The main difference between a phone falling from the sky versus from someone’s hand is the speed at which the phone hits the ground, as objects accelerate as they fall.

A fall from higher up means more time to speed up – to a point.

For example, a phone falling from 4 feet would be traveling at around 10 mph when it hits the ground, whereas a phone falling from 16,000 feet would be traveling at about 60 mph.

And then there’s air resistance to take into consideration.

When air resistance reaches the same magnitude as the Earth’s gravitational force, the object stops accelerating and falls at a constant speed, otherwise known as terminal velocity.

But whether a phone’s screen breaks is determined by the end of the fall – in other words, what it lands on, and the way it lands.

There’s a big difference between a phone landing on a pillow – which compresses beneath the phone – versus landing on concrete – where there’s no give.

Last but not least, glass innovations make a big difference, too.

The vast majority of smartphone manufacturers, including Apple, Samsung, Sony and Google, opt to use a popular Gorilla Glass.

In Apple’s case, the past few generations of the iPhone, starting with the iPhone 12, have used a different technology called Ceramic Shield.

According to Apple, this kind of screen is more durable than previous iPhone screens.

And the iPhone found on the side of the road appeared to be a relatively new model, so the screen will have benefitted from whatever new and improved glass-strengthening techniques Apple was using.

Given the right set of circumstances, the fact that a phone survived a skydive without a case, like the latest iPhone accessory, isn’t so wild.

What’s more amazing, though, is the fact that it was found unlocked, with half its battery, and still in airplane mode.
